Question

subtract the two expressions

Answer 1

\[\frac{ x+4 }{ 2x } - \frac{ x }{ x-4 }\]

Answer 2

Oh, this is trickier than the last one!

Answer 3

yeah...

Answer 4

I have to look at this for a little bit..

Answer 5

\[\frac{x+4}{2x}-\frac{x}{x-4}\]
Least common denominator.
\[(\frac{x+4}{2x})\frac{x-4}{x-4}-(\frac{x}{x-4})\frac{2x}{2x}\]
\[\frac{x^2-16}{2x(x-4)}-\frac{2x^2}{2x(x-4)}\]
Now add normally.

Answer 6

Wow.... Why didn't I think of that immediately? Thanks! :)

Answer 7

By add I mean subtract. Or maybe add negatively?

Answer 8

Haha, that works!
